Refraction-enhanced x-ray radiography (REXR) is used to infer shock-wave positions of more than one shock wave, launched by a multiple-picket pulse in a planar plastic foil. This includes locating shock waves before the shocks merge, during the early time and the main drive of the laser pulse that is not possible with the velocity interferometer system for any reflector. Simulations presented in this paper of REXR show that it is necessary to incorporate refraction and attenuation of x rays…

Quantitative phase contrast imaging of a shock-wave with a laser-plasma based X-ray source

The application of a polychromatic X-ray laser-plasma source to the study of a laser-driven shock travelling in plastic material allows for a clear identification of the shock front as well as of small-scale features present during the interaction.
